| 熔喷无纺布的口罩主要作用于喷漆类，有毒有害工业，及化学工业等。 Melt blown non-woven facemasks are mainly used in paint spraying, toxic and harmful industries, and chemical industries. 口罩主要是起到防护的作用，针对防护要求不同，选用的口罩类型也不同，普通平面口罩一般由三层组成，上下两面都是pp无纺布，中间一层是起防护作用的熔喷布，一般选用20克重的；而n95杯型口罩则由针刺棉、熔喷布、及无纺布组成，其熔喷布通常采用40克重甚至更高，再加上针刺棉的厚度，所以外观上看起来比平面口罩更厚一些，其防护效果至少能达到95%。 Masks mainly play a protective role, in view of different protection requirements, the types of masks used are also different. Ordinary flat masks generally consist of three layers, the upper and lower sides are PP non-woven, the middle layer is a protective melt-blown cloth, generally 20 grams of weight; while N95 cup masks are composed of needle-punched cotton, melt-blown cloth and non-woven cloth, the melt-blown cloth usually uses 40 grams of very heavy. To a higher level, combined with the thickness of needle-punched cotton, it looks thicker than a flat mask, and its protective effect can reach at least 95%. |
